This paper deals primarily with the validation of a clean-up procedure based on anion exchange solid-phase extraction for the accurate determination of glutathione peroxidase (GPx), selenoprotein P (SelP) and selenoalbumin (SeAlb) in human serum by affinity HPLC (AF-HPLC) coupled to inductively coupled plasma-mass spectrometry (ICP-MS). In addition, the identification and the purity assessment of the GPx, SelP and SeAlb peak fractions separated by AF-HPLC is addressed by their analysis using matrix assisted laser desorption ionization-time of flight mass spectrometry. © 2010 The Royal Society of Chemistry.
